Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452356, here are decompositions:

73 + 31452283 = 31452356
157 + 31452199 = 31452356
277 + 31452079 = 31452356
337 + 31452019 = 31452356
349 + 31452007 = 31452356
487 + 31451869 = 31452356
499 + 31451857 = 31452356
643 + 31451713 = 31452356

Showing the first eight; more decompositions exist.
